Why not changed it to the new 18F USB parts (also need
to change the oscillator to 4Mhz or multiply of 4MHz)?

Then the limit code size of PIC16C745 will not be a limit
factor. Even better we can make use of the USB bootloader
so that the firmware can be updated.

Of course, this becomes a major project then.

Indeed; software can be modified more easily than written.  Sometimes.
I once modified a LISP program!  Shudder.  System utilities shouldn't
be written in LISP...

In this case, at least part of the programming algorithm is going to be
in the 16C745 on the pickit1 itself, and that will probably limit the
range of PICs you can program somewhat.
